Overclocking?

I'm a newbie,  when it comes to Overclocking...
I want to Overclock my AMD 64-bit 3000+ (( 2ghz )),  I'm aware you have to go into the BIOS,  but after that... I'm clueless;  Can someone point me in the right direction?

I can get a 20% overclck on my processor, from 2.0 to 2.4 ghz. I have this thing that most overclockers call agp/pci locks. No matter what i set the front side bus to, the agp bus will stay at 66, and the pci bus will stay at 33. As i said, the only issue is heat, so it is not just a few mhz here and there.  Mabee you should look into the nForce 3 250gp chipset.  It can do as i say and it wont disrupt the rest of the system.  The main thing that will hold you back is your ram.  Mine is the PQI Turbo series and i can take it from 400mhz to 480+. Thats how you overclock.
